Actually, freedom of religion according to the Constitution means that Congress cannot pass any laws respecting the establishment of religion, e.g. Congress cannot deem Christianity, Judaism, Buddhism, Islam or any other religion as official nor can they create a State religion. It also prohibits the government from interfering with the practice of one's religion so long as it is practiced within the laws of the United States. Abortion and gay rights has less to do with religion than it does the American value of life (hence the right to life, liberty and the pursuit of happiness in the Declaration of Independence and the right to life, liberty and property under due process of the law according to the 14th Amendment of the Constitution)The limitations on religious freedom primarily come in where there is a conflict between the practice of religion and local, state or federal laws. And in rare instances when a child's health depends on medical treatment that a particular religion otherwise prohibits, the Courts may decide to overrule religious freedom of the parents for the safety, health and welfare of that child.Freedom of religion is not limited by hate speech, in fact, hate speech is not limited at all. It is still a part of the protections afforded under the 1st Amendment.
